[GraphHopper] Shortest route (not fastest) from Paris to Rome

[Peter]

Hi Geoffrey,

Yes, sure. If you use CH do before the import:
hopper.setCHShortest("shortest")
// on master this is called setCHWeighting

if you use GH without CH you can change this per request
ghRequest.setWeighting("shortest")

What you are after are probably more 'alternative routes', this is not
yet included but will at some point (and in some dev branch if you need
more details)

Kind Regards,
Peter.
